regulator: palmas: Fix calculating selector in palmas_map_voltage_ldo
This patch fixes below issues when choosing selector:
1. Current code returns negative selector if min_uV < 900000 which is wrong.
For example, it is possible to satisfy the request with selector = 1 if
the requested min_uV is 850000.
2. Current code may select a voltage lower than requested min_uV.
For example, if the requested min_uV is 945000, current code chooses
selector = 1 which is lower than requested min_uV.
DIV_ROUND_UP to avoid this case.
